I have the car below in my sig and could either get a rebuild t-5 built to 90-93 factory specs or one rebuilt to ford racing t-5 specs, the 330ft# one. I'm looking to get around 300 to the rear wheels eventually and was wonder what you guys that drag race a couple times of month have done to your t-5s if anything?
As far as I have heard, powershifting destroys T-5's. If you don't launch at above 3000 rpm with slicks and don't powershift, then the T-5's should last a little while at least 
thats it!!!!!!!!!!!! (of topic)
